K, and Mg imbalance

1. Description of the problem Disorders of potassium: overview Potassium (K) is an essential intracellular cation. 98% of total body K is intracellular; it is a main determinant of intracellular osmolality, and its transmembrane gradient regulates cell membrane resting electrical potential. Intracellular concentration of K (100-150 mEq/L) is maintained via an active Na/K ATPase membrane…
